Assessment of Cu, Zn content in fluvisol of Red river and Thai Binh river
Analyse results from 24 fluvisols soil samples on total and available Cu, Zn: total Cu content change 18.00ppm – 43.50ppm, total Zn content 42.25ppm – 119.50ppm. all 24 samples is not polluted, but fluvisols in Thanh Tri may have been affected of Cu and Zn metal. Content of available Cu in 24 soil samples is 9.41ppm – 17.80ppm and available Zn 7.96-29.95ppm. they don’t depend on the content of total Cu, Zn, but depend on some characteristics of soils. This available Cu content may be toxic for plant. Between total Cu and total Zn is a positive correlation, r=0.92.
